Husband having SCT on 12/22 as an outpatient. We have 3000 sq. ft house and I have someone coming to install blinds for an hour on Jan.4 in a completely different bedroom and area with its own entrance from where he will be. I will have installer mask etc. Is this safe and what about my house cleaners that come 2x a month? I need this service especially then. Also, if he is staying in a room with no houseplants , is it okay to keep them in another room? These have been here- no new ones. Please advise.
